Did you know that many inventions began as accidents?
Some of these accidents even became big business ideas.
They gave us products that people all over the world use every day.
In 1886, in the United States, a pharmacist named Dr. John Pemberton tried to invent a
medicine.
Pemberton wanted a cure for headaches.
He mixed several ingredients together.
No one knows exactly what he did.
The mixture was a mystery, but it tasted delicious.
Pemberton took the mixture to a drug store.
The drug store sold the medicine as a drink for a few cents a glass.
Pemberton and a partner started a company to make and sell the drink.
However, the business didn't make much money.
Then a smart businessman named Asa Candler bought the company.
Candler made the business much more successful.
The company grew and it sold the drink around the world.
What happened to the mysterious headache cure?
It's now a global product.
It's one of the most famous brands in the world, Coca-Cola.
The Coca-Cola company markets the drink in 200 countries.
It sells more than 1.6 billion drinks every day.
An accident with a candy bar became another business idea in the United States.
It happened in 1946.
Percy Spencer, an engineer, put a candy bar in his jacket pocket.
Then he went to work.
That day he was testing a magnetron in his company's laboratory.
The company used magnetrons to make radar systems.
A magnetron is a device that produces microwaves.
These are short waves of energy that cause things to heat up.
Spencer stood near the magnetron.
He turned it on.
Suddenly, something very strange happened.
The candy bar in his pocket melted.
Spencer thought, maybe I could try this with other foods.
First, he put little pieces of dried corn near the magnetron.
Soft white puffy popcorn flew all around the room.
Then he put an egg next to the magnetron.
It heated up quickly and exploded.
Spencer got hot yellow egg yolk all over his face.
Some of Spencer's experiments were messy, but he discovered a new way to cook.
What did he invent?
The Microwave Oven.
The early microwave ovens were enormous.
They were about 5.5 feet, 1.7 meters tall.
And they weighed over 750 pounds, 340 kilograms.
They cost about $5,000 each.
They were only good for restaurant use.
Today, manufacturers make small, lightweight microwave ovens that are much cheaper than
the early ones.
These days, over 80% of homes in the developed world have a microwave oven.
Coca-Cola and the microwave oven were lucky accidents.
There are other examples too.
Did you know that the invention of plastic was an accident?
The Post-it note is another example.
Now people use millions of these small, sticky pieces of paper in offices and homes around
the world.
Will other accidents bring us successful business ideas in the future?
Who knows?
The lucky scientific accident is happening somewhere in the world right now.
